A conductor with rectangular cross section has
\( \mathrm{P} \) dimensions \( (\mathrm{a} \times 2 \mathrm{a} \times 4 \mathrm{a}) \) as shown in figure.

W Resistance across \( \mathrm{AB} \) is \( \mathrm{x} \), across \( \mathrm{CD} \) is \( \mathrm{y} \) and across \( \mathrm{EF} \) is \( z \). Then
(1) \( x=y=z \)
(2) \( xyz \)
(3) \( yxz \)
(4) \( xzy \)
